Muscles of the Forearm that Move the Hand and Fingers

1.1K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Area of Science:

  • Robotics
  • Mechanical Engineering
  • Materials Science

Background:

  • Stable grasping in robotics is crucial for automation.
  • Current grippers often struggle with diverse object shapes and materials.
  • Soft interactions are increasingly important for delicate object manipulation.

Purpose of the Study:

  • To introduce a novel robotic gripper design for universal object grasping.
  • To investigate the effectiveness of a hybrid mechanism combining soft structures and skeletal support.
  • To evaluate the gripper's performance across a wide range of object types and properties.

Main Methods:

  • Designed a novel gripper featuring a hybrid mechanism with granular pouches on finger skeletons.
  • Conducted experiments using fifteen distinct object types (e.g., cylinders, spheres, irregular shapes).
  • Assessed gripper performance based on success rates for objects up to 210g.

Main Results:

  • The granular-tendon gripper demonstrated high success rates for objects under 210g.
  • The hybrid design successfully adapted to various object shapes and material properties.
  • The gripper provided both stability through skeletal support and adaptability via soft granular pouches.

Conclusions:

  • The developed gripper offers a promising solution for versatile robotic manipulation.
  • The hybrid design enables stable and soft grasping, accommodating object variability.
  • This approach enhances robotic capabilities in handling diverse items.
